Hole N' The Rock

Hole N' The Rock, situated in Utah’s Canyonlands Country, is a 5,000-square-foot home dating back to the 1940s. The house was dug out and carved by Albert Christensen for 12 years before he moved his family in.

After he passed away, his wife continued living in the rock until she passed away. Today, the area includes 14 different rooms, a fireplace with a 65-foot chimney, and a bathtub built right into the rock.

Winchester Mystery House

After the death of her husband and children, a woman named Sarah Winchester purchased an unfinished farmhouse, and over the next 38 years, turned it into the fascinating attraction it is today.

The Mystery House in San Jose, California, is a home of architectural oddities that include stairs that lead to nowhere (to a dead end or a wall), doors that do the same, a grand ballroom that was created using almost no nails, and miles of secret passageways. Some say she built the house this way to confuse evil spirits.

The House On the Rock

Originally opened in 1959, The House On The Rock is a unique architectural complex that houses some of the world's most bizarre and biggest collection of strange objects.

The attraction has everything from huge replicas of sea monsters to music machines that play as you explore the various dimly lit rooms. A massive carousel sits in a room that also houses more than 180 chandeliers.

Ben and Jerry's Flavor Graveyard

Ben and Jerry’s has had a lot of flavors throughout the years, and to pay tribute to those that just didn't make the cut, the ice cream company created the Flavor Graveyard at their factory in Waterbury, Vermont.

Opened in 1997, the graveyard features resin headstones with clever commentaries on the "lives" of each flavor, some of which are brought back to market from time to time.

The Museum of Bad Art

The Museum of Bad Art, like its name suggests, is dedicated to showcasing art of questionable value. MOBA has various locations throughout Massachusetts and a collection of around 600 pieces (though 50-70 are shown in exhibits at a time).

Each piece has a narrative to go along with it. They range from the image above, of Kennedy eating ice cream, to a cat daydreaming of a dog.

The JELL-O Gallery Museum

If you've ever wondered where one of America's most famous desserts, Jell-O, came from, then head to the JELL-O Gallery Museum in LeRoy, New York. The museum is dedicated to the dessert, delving into its history and production over the years.

Bubblegum Alley

Though there are bubblegum walls in several locations across the US, the Bubblegum Alley in San Luis Obispo, California, stands 65 feet long and 15 feet high, and has been covered in chewing gum for years.

When the local business association attempted to have it cleaned in the 1990s, they were refused, and the alley was left in all its gum-filled glory.

National Mustard Museum

The National Mustard Museum in Middleton, Wisconsin, has all things related to the popular condiment.

Currently, the museum has more than 5,000 mustards from all 50 states and from more than 70 countries on display. There are also antique tins, jars, and vintage advertisements. The museum also hosts various mustard-related competitions and events throughout the year.

World's Largest Ball of Twine

Multiple US destinations have long been competing for the title of the world's biggest ball of twine. There are several claims to which is the biggest, with the most recent indication in 2014 that it's in Cawker City, Kansas.

Started by Frank Stoeber in 1953, the ball of twine weighed a staggering 19,873 pounds the last time it was measured in 2013. Plus, each year a twine-a-thon is held to add more twine into the mix, only helping it to grow larger.

Cadillac Ranch

Cadillac Ranch has become one of America's most iconic roadside attractions.

Located along Route 66 in Amarillo, Texas, the art installation includes ten Cadillacs that are half-buried with their noses down, supposedly at the same angles as the Great Pyramid of Giza. Splattered in paint, the vehicles still baffle and amaze travelers today.
